Principle: AFM is a precision finishing process that removes burrs, polishes surfaces, and improves edge uniformity by forcing a viscous abrasive media through a workpiece under pressure.Key Components:Abrasive Media: A semi-solid polymer carrier mixed with abrasive particles (SiC, Al₂O₃, or diamond) that conforms to complex geometries.Hydraulic/Pneumatic System: Drives the media in a controlled bidirectional flow through the part.Tooling/Fixtures: Custom-designed to direct media flow precisely over target surfaces.Process Parameters:Abrasive Type & Grit Size (coarse for deburring, fine for polishing).Media Viscosity (affects flow behavior and material removal rate).Extrusion Pressure (higher pressure increases cutting aggressiveness).Cycle Time & Number of Strokes (determines final surface finish).Advantages:Finishes intricate/internal passages (e.g., cross-holes, molds).No thermal damage (cool process).Improves fatigue resistance by creating compressive residual stresses.Applications: Aerospace (turbine blades), automotive (fuel injectors), and medical (implants).
The one-way automatic circulating fluid polishing machine uses the lower hydraulic cylinder to move and squeeze,so that The soft abrasive is extruded from the same inlet and from other channels,and repeatedly ground to To achieve the purpose of polishing,deburring and chamfering.This processing method is applicable to all kinds of curved flow channels, elbows or slender pipes,and large internal Cavity and other work pieces that are not easy to polish,or precision parts to remove cross hole burrs,is the most important Suitable processing method. And the grinding direction is consistent,which can effectively improve Performance,quality and service life of the die or work piece.After polishing, the finish can reach the mirror grade, and the best surface roughness can reach ra0.2μm.Abrasive Flow Machining is used for producing high-quality surface finishes on internal and external contours, for targeted precision deburring and defined edge rounding or the precise deburring of intersections.
